100 Delete Configurations
101 [Documentation] Delete all elements that were created in the test case section. These are done
102 ... in a local keyword so this can be called as part of the Suite Teardown. When called as part
103 ... of the Suite Teardown, all steps will be attempted. This prevents robot framework from bailing
104 ... on the rest of a test case if one step intermittently has trouble and fails. The goal is to attempt
105 ... to leave the test environment as clean as possible upon completion of this suite.
